PD-L1 and PD-1 were expressed variably in DLBCLs by tumour cells and tumour-infiltrating immune cells and might be potential therapeutic targets using PD-1/PD-L1 blockade.

Programmed cell death (PD)-1/PD-1 ligand-1 (PD-L1)-targeted therapy has emerged as a promising therapeutic strategy for lung cancer. However, whether EML4-ALK regulates PD-L1 expression in lung cancer remains unknown. A total of 532 pulmonary adenocarcinomas (pADCs), including 58 <i>ALK</i>-translocated tumors, were immunohistochemically evaluated for PD-L1 and PD-1. H23 (<i>EGFR</i>^Wild-type<i>EML4-ALK</i>^-PD-L1^Low) and H2228 (<i>EGFR</i>^Wild-type<i>E

Tumor-associated macrophages (TAMs) and regulatory T-cells (Tregs) play an important role in the tumor microenvironment. Here, we investigated the prognostic implications of TAMs and Tregs in 165 diffuse large B-cell lymphomas (DLBCLs) using immunohistochemistry. Survival analysis was performed among 109 DLBCLs treated with rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP). An increase in CD68 (+) cells was related to improved overall survival (OS) (p = 0.033). By con

Pellino-1 is an E3 ubiquitin ligase acting as a critical mediator for a variety of immune receptor signaling pathways, including Toll-like receptors, interleukin-1 receptor and T-cell receptors. We recently showed that the Pellino-1-transgenic (Tg) mice developed multiple tumors with different subtypes in hematolymphoid and solid organs. However, the molecular mechanism underlying the oncogenic role of Pellino-1 in solid tumors remains unknown. Pellino-1-Tg mice developed adenocarcinoma in the l
